 f(x)=66x; g(x)=3x+6 f\left(x\right)=6-6x;\ g\left(x\right)=-3x+6\   Find  f+g(x)f+g\left(x\right)  

 (f+g)(x)=9x+12\left(f+g\right)\left(x\right)=-9x+12  

 (f+g)(x)=3x\left(f+g\right)\left(x\right)=3x  

 (f+g)(x)=3x+6\left(f+g\right)\left(x\right)=-3x+6  

 (f+g)(x)=3x+12\left(f+g\right)\left(x\right)=-3x+12
